New version of the plugin does not work on Windows

[AngelEzquerra]

The new version of the plugin does not work well on Windows. The syntax highlighting works, put none of the nimlanguageserver based features work. In particular:

• While it prompts you to confirm that you want to install nimlangserver if it is not installed, the installation does not seem to complete.
• One you install it and restart you get several error messages:
• Whenever you save a file you get an error indicating that nim is not on the path, even though it is (you can see that message on the screenshot above). I confirmed that nim really is in the path by opening a command line and doing echo %PATH% and confirming that the folder that contains the nim executable is in the list. I also ran which nim which showed me the path to nim.exe. Finally I also nim --version which returned the following:

  C:\repositories\nim_tests\impulse\impulse>nim --version Nim Compiler Version 2.1.9 [Windows: amd64] Compiled at 2024-07-24 Copyright (c) 2006-2024 by Andreas Rumpf

  active boot switches: -d:release

These problems happen for every nim file I open. I ran nimble dump on the folder of one of the files and I got the following result:

C:\repositories\nim_tests\impulse\impulse>nimble dump packageinfo.nim(280) findNimbleFile

Error:  Could not find a file with a .nimble extension inside the specified directory: C:\repositories\nim_tests\impulse\impulse

Can you install this custom version? (you need to unzip it). On startup it should print in the Nim output log "The value of ext.nimDir.." which will help debugging your issue nimvscode-1.0.0.vsix.zip Thanks!

Thanks for creating this debug version for me, and sorry for taking a while to be able to test it. This is what I got on the Nim panel after installing that debug version:

2024-07-02 0012:0013:0057.000225 - nimlangserver found: C:\Tools\Development\.nimble\bin\nimlangserver.exe

And on the Nim Language Server Panel I see the following:

The issue was fixed by cloning the nim language server repo, building it and replacing nimlangserver.exe with the result of that build. With that the extension does not generate any errors and mostly works although a few things don't (e.g. inline hints). Thanks to @jmgomez for helping me fix the issue!
